Storage Redundancy (1 / 16):

Your company is a global e-commerce giant, running a large-scale application on Azure that serves users around the world. They store massive amounts of transactional data that can't be easily regenerated and is crucial for their business. Their operations aren't restricted by any specific data governance regulations.

What type of Azure storage redundancy should your company consider for their high data availability and durability requirements?
How does the recommended storage redundancy option ensure high data availability and resilience to data loss?
What potential drawbacks could there be if your company chooses Locally Redundant Storage instead?

Answer:

Your company should consider using Geo-Redundant Storage (GRS) because it provides the highest level of data resilience available in Azure. Given the crucial nature of their data, it's essential that they have a high level of redundancy.
GRS replicates data to a secondary, geographically distant Azure region, which ensures data availability even in the case of a complete regional outage. In addition, GRS maintains six copies of the data (three in the primary region and three in the secondary region), which provides a high level of data durability and protection against data loss.
If your company opted for Locally Redundant Storage (LRS), they would risk losing all their data in the event of a catastrophic failure at the data center or a disaster that impacts the entire region.
